If you have two identical center channel speakers, what would be the disadvantages to using two bi-wired center channels? When I hook up two, the center channel seems MUCH more pronounced, the dialog is WAY more audible. (my speakers do not have dual binding posts btw) Is there any problem with doing this?

1. There is no disadvantage to using bi-wired center channels over using 2 center channels. The damage is already done. ;-)

2. If you do not have 4 binding posts on each speaker, you cannot biwire those speakers.

Not again...


EDIT:


I just realized, that wasn't very helpful.... or friendly.... or both, actually.


I think you are not using the term "bi-wire" correctly. Would you like to post a schematic or a more detailed description of what exactly you are trying to do?

I'm not quite sure what you're proposing either...but the fact that you're talking about using two centers suggests that you're headed down the wrong road. Or at the very least, they you're heading away from conventional wisdom.


Paging sivadselim....sivadselim to the speaker forum for the "canned" write-up on dual centers please...


He should be right along.


But seriously...as Val asked, what are you trying to accomplish? There might be a better solution once the problem is a little clearer.

I just wanted to know if it would ruin my soundstage or degrade my sound quality by hooking up dual center channels. I would have two wires coming from my center channel binding posts on my receiver, one for each center channel.

Yes. This has been proposed and discussed more than a dozen times here on AVS.

You need two wires (+ and -) for each speaker, not one for each.

Been there, argued that, etc. and so on. Just try it, and if it sounds better to you, then stay with it. If you want to know WHY it shouldn't sound better stick around, and someone will explain it!

Well, sivadselim will probably post his summary of the issue which is already posted many times. If not, try searching for the topic. It's there.

Ah, I see - I did try searching before posting this thread but I couldn't find much - sorry.

Not much to say here except don't use two center channel speakers. Using two centers creates unwanted acoustic anomalies (how's that for catch-all?). You use one speaker for every other channel, so should you with the center.


And, as pointed out, what you're describing is not bi-wiring. Connecting two centers to two amp channels of the receiver in parallel presents the combined impedance of both centers to the amps.

If you're not happy with your current center, then just drop it and use the phantom center setting on your equipment.


It will sound much better than a crappy sounding center or trying to do something silly.

Ok, if you won't do it, I will quickly.


When any two speakers reproduce the same signals, the summed radiation pattern is irregular and eccentric in the plane of their displacement. So, two centers placed side by side will result in a less even sound and integrate less well with the L and R speakers.

Crap, you left an opening for the question about vertical placement that is coming next.

This is pretty good advice provided your center channel speaker is truly that inferior to your fronts and you have tried everything else to get it to sound better; i.e. mainly correct calibration and optimum (or better) room placement. Placing it in or on a shelf and/or near the floor is going to affect its sound detrimentally.

It's my didactic tool. I always try to leave my students with a need to ask more.

Then what should I place the center channel on? I love my center, no way do I want a phantom center channel. (all I wanted to know was if bi-amping them was a bad idea, and it turns out it's a horrible idea)

I did that.

worked great...same as you.

i switched it back , and my family asked me "what's wrong with the sound?"


so now i live with two center channels...not much you can do except live with the better sound...
